What is this bump and scab on my cat's head, now bald?
It looks like she make have gotten a small wound on her head, maybe from getting swatted by another cat. Cat claws and bites tend to make wounds with small holes that seal over and trap bacteria inside. This will form a small abscess which will then rupture, which is what this appears to be to me. Keep an eye on it and keep it clean with a washcloth, warm water and a mild soap. Clean it two or three times a day and make sure to get all the soap off or it will irritate her skin. As long as it continues to improve and she is acting fine, eating and drinking, she should be fine. If it closes up again, swells, gets really red, hot, or if she starts acting sick or loses her appetite, get her in to see you vet as soon as possible as she may then need antibiotics to clear up the infection and heal.
